flushdraw,from an old bass players'point of view,i can only relate at how i arrived at purchasing a sub.my room is 19' x
13'(medium)i listened to 8-10-12" powered subs(mirage,
purchased before i new about axiom)i found the 8" a little
thin,the 12",when pushed,a little cluttered,and ended up
buying the 10"(very clean,ample power)i listen to 60% theater,40%music,and have not regretted the purchase since.
hope this helps.
